Abstract

Procédé de fabrication d'une membrane minérale sur un support minéral comportant la fabrication d'une dispersion comprenant une charge et une résine, le dépôt de cette dispersion sur le support de manière à former une couche, le traitement thermique du support revêtu de ladite couche, caractérisé en ce que, de manière à obtenir une membrane asymétrique de faible épaisseur,

  • on prépare une dispersion fluide comprenant une charge, un solvant soluble dans l'eau, une résine insoluble dans l'eau mais soluble dans le solvant organique et donnant après cokéfaction un taux de coke supérieur à 20 % en poids
  • on la dépose sur ledit support minéral
  • on déplace tout ou partie dudit solvant pour précipiter la résine
  • on cokéfie la résine et éventuellement le support.
A method of manufacturing a mineral membrane on a mineral support comprising the manufacture of a dispersion comprising a filler and a resin, the deposition of this dispersion on the support so as to form a layer, the heat treatment of the support coated with said layer , characterized in that, so as to obtain an asymmetrical membrane of small thickness,
  • a fluid dispersion is prepared comprising a filler, a water-soluble solvent, a resin insoluble in water but soluble in the organic solvent and giving after coking a coke content of more than 20% by weight
  • it is deposited on said mineral support
  • all or part of said solvent is displaced to precipitate the resin
  • the resin and possibly the support are coked.
